Obiettivo

Intumescent coatings are applied to steel to provide insulation in the event of a fire and are usually applied on-site. The application of the coating, however, is on the critical construction path and there is a trend towards off- site application. The current generation of thin film intumescent coatings has a number of weaknesses for off-site application and these are in part inhibiting the use of steel in the construction industry. The principle objectives of the project are: to develop alternative resin technologies for the production of thin films intumescent coatings with superior fire resistance, and durability; to undertake full scale fire tests to validate the performance of the new systems; to understand the mechanisms by which intumescent coatings degrade during both storage and usage; to audit the application, transportation and construction phases of intumescent coated steelwork; to assess the effect of any coating damage on the fire resistant properties of the steelwork.
